My parents put an outside entertainment center in the awning side of their RV. "Nothing too crazy" Just a 20" tv, an Xbox, a deck, and a couple 8" speakers... I must say it turns a lot of heads, and is great when you want some outside music in the evenings while cooking dinner, etc. There's nothing more embarrassing than a boom box at a camp site!
Greg, it is also a seller if you're trying to get the grandkids to come along.
You won't see me towing to the track with it anytime soon...my dad won't let me within 10 feet of the captain's chair, haha.
